NodeJS：运行dot slash命令行Windows

Question

I'm trying to get the following code which should execute shell command to wor in OSX and Windows.

const exec = require("child_process").exec;
const runCommand = (cmd) => exec(cmd,
    function (error, stdout, stderr) {
        if (stdout.length > 0) {
            console.log(stdout);
        }
    });

For the following runCommand("./node_modules/.bin/someBinary") it does not work in Windows. But it works fine in OSX. So I wonder what modifications do I need for it to run in Windows as well?

Answer 1

Have you considered giving a try at npm-exec ?

Loads the same environment that would be present for npm run-script , but executes arbitrary bash command lines. (even on windows! Thanks to bashful). This includes modifying $PATH so scripts in node_modules/.bin will be used before global modules.

So you could npm-exec someBinary instead of using a relative path breaking Windows / OSX compatibility

If this module does not suit you, you can also give a try at npm bin as explained in this answer .

Answer 2

Okay, so in the end I solved it with checking which platform I'm in and in turn I just wrote the same command with OS specific so it would run.

In short I used process.platform to find out which OS it is. Not the most elegant. But at least it solved my problem.
